This release aggregates all the changes occurred between official
releases in 0.4 series and various snapshot releases (in 0.5 and 0.6
series). To get better overview of high level changes see

Fixes (23 BF commits)

significance level in the right tail was fixed to include the
value tested -- otherwise resulted in optimistic bias (or
absurdly high significance in improbable case if all estimates
having the same value)

Various improvements and increased flexibility of null distribution
estimation of Measures.

All attribute are now reported in sorted order when printing a dataset.

fmri_dataset now also stores the input image type.

Crossvalidation can now take a custom Splitter instance. Moreover, the
default splitter of CrossValidation is more robust in terms of number and
type of created splits for common usage patterns (i.e. together with
partitioners).

CrossValidation takes any custom Node as errorfx argument.

ConfusionMatrix can now be used as an errorfx in Crossvalidation.

LOE(ACC): Linear Order Effect in ACC was added to
ConfusionMatrix to detect trends in performances across
splits.

A Node s postproc is now accessible as a property.

RepeatedMeasure has a new 'concat_as' argument that allows results to be
concatenated along the feature axis. The default behavior, stacking as
multiple samples, is unchanged.

Searchlight now has the ability to mark the center/seed of an ROI in
with a feature attribute in the generated datasets.

String summaries and representations (provided by __str__
and __repr__) were made more exhaustive and more coherent.
Additional properties to access initial constructor arguments
were added to variety of classes.

Also adapts changes from 0.4.6 and 0.4.7 (see corresponding
changelogs).

0.6.0~rc2 (Thu, Mar 3 2011)

Various fixes in the mvpa.atlas module.

0.6.0~rc1 (Thu, Feb 24 2011)

Many, many, many

evolving release notes for 0.6 <chap_release_notes_0.6>

0.5.0 (sometime in March 2010)

This is a special release, because it has never seen the general public.
A summary of fundamental changes introduced in this development version
can be seen in the :ref:release notes <chap_release_notes_0.5>.

Most notably, this version was to first to come with a comprehensive two-day
workshop/tutorial.

0.4.7 (Tue, Mar 07 2011) (Total: 12 commits)

A bugfix release

Fixed

Addressed the issue with input NIfTI files having scl_ fields
set: it could result in incorrect analyses and
map2nifti-produced NIfTI files. Now input files account for
scaling/offset if scl_ fields direct to do so. Moreover upon
map2nifti, those fields get reset.

:file:doc/examples/searchlight_minimal.py - best error is the
minimal one

Enhancements

:class:~mvpa.clfs.gnb.GNB can now tolerate training datasets
with a single label

:class:~mvpa.clfs.meta.TreeClassifier can have trailing nodes
with no classifier assigned

0.4.6 (Tue, Feb 01 2011) (Total: 20 commits)

A bugfix release

Fixed (few BF commits):

Compatibility with numpy 1.5.1 (histogram) and scipy 0.8.0
(workaround for a regression in legendre)

About:
Scilab Pattern Recognition Toolbox is a toolbox developed for Scilab software, and is used in pattern recognition, machine learning and the related field. It is developed for the purpose of education and research.

About:
FLANN is a library for performing fast approximate nearest neighbor searches in high dimensional spaces. It contains a collection of algorithms we found to work best for nearest neighbor search.

About:
dANN is an Artificial Intelligence and Artificial Genetics library targeted at employing conventional techniques as well as acting as a platform for research & development of novel techniques. As new techniques are developed and proven to be effective they will be integrated into the core library. It is currently written in Java, C++, and C#. However only the java version is currently in active development. If you want to obtain a version other than the java version you will need to get it directly from GIT.

About:
GIDOC (Gimp-based Interactive transcription of old text DOCuments) is a computer-assisted transcription prototype for handwritten text in old documents. It is a first attempt to provide integrated support for interactive-predictive page layout analysis, text line detection and handwritten text transcription. GIDOC is built on top of the well-known GNU Image Manipulation Program (GIMP), and uses standard techniques and tools for handwritten text preprocessing and feature extraction, HMM-based image modelling, and language modelling.
